[0018] The following will further specifically describe the specific embodiments of the present utility model through specific embodiments in conjunction with the accompanying drawings.

[0019] Embodiment 1:

[0020] An outdoor landscape lamp, as Figure 1 shown, mainly includes a housing and internal components, and the overall shape of the lamp body is cylindrical. The housing mainly includes a lamp cover 1, a left end cover 5, a right end cover 6, a ceramic heat dissipation plate 88, etc. The lamp cover 1 is cylindrical with openings at both ends and is sealed by the left end cover 5 and the right end cover 6. Approximately one-fourth of the side of the lamp cover 1 is an opening, and this part of the opening is sealed by the ceramic heat dissipation plate 88. The ceramic heat dissipation plate 88 is generally flat and matches the size of the opening on the side of the lamp cover 1, and can just completely seal the opening. The lamp cover 1 is overall transparent, while the left end cover 5, the right end cover 6, and the ceramic heat dissipation plate 88 are all opaque, and the light inside the lamp body diverges from the lamp cover 1.

[0021] An aluminum heat sink 4 is provided inside the lamp body. The overall shape of the aluminum heat sink 4 is similar to that of the lamp cover 1, and there are some grooves on the surface. The connecting line of its outermost border just coincides with the inner connecting line of the lamp cover 1. Some of the grooves on the surface of the aluminum heat sink 4 are positioning grooves 402 for fixing the light-emitting lamp strips 3, and the number of the positioning grooves 402 coincides with the number of the light-emitting lamp strips 3. There are four light-emitting lamp strips 3 in this embodiment, and the number of the positioning grooves 402 is also set to four and is evenly distributed. All the light-emitting lamp strips 3 are connected by lamp strip connectors to form a whole. The size of the positioning grooves 402 matches the shape and size of the light-emitting lamp strips 3. When the light-emitting lamp strips 3 are fixed in the positioning grooves 402, the blocking blocks slightly extending from the top of the positioning grooves 402 to the inside of the groove body of the positioning grooves 402 can prevent the light-emitting lamp strips 3 from running out of the positioning grooves 402 and thus being misaligned. An aluminum heat sink 4 clamping groove 403 is provided inside the aluminum heat sink 4, and the width of the clamping groove 403 matches the width of the circuit element fixing plate. The circuit element fixing plate is fixed in the clamping groove 403, thus presenting a relatively suspended state. On the side of the circuit element fixing plate facing the inner cavity of the aluminum heat sink 4, there are various components of the control circuit 7. Therefore, the control circuit 7 is located between the aluminum heat sink 4 and the ceramic heat dissipation plate 8, and can dissipate heat from the control circuit 7 to the greatest extent and protect the operation of the circuit.

[0022] On the upper positions of the openings on both sides of the outside of the aluminum heat sink 4, there are distributed and provided with a fitting groove 404, forming a right L-shaped barb. On the inner side of the ceramic heat dissipation plate 8, there are provided two parallel limiting strips 801, and the limiting strips 801 can match the shape of the groove body of the fitting groove 404. During installation, the limiting strips 801 are fitted in the fitting groove 404 to prevent the position of the aluminum heat sink 4 from shifting.

[0023] On the inner sides of the left end cap 5 and the right end cap 6, there are irregular shapes protruding inwards. These irregular shapes match the shapes at both ends of the aluminum radiator 4, allowing the aluminum radiator 4 to be just fitted into the irregular shapes, preventing the aluminum radiator 4 from rotating, which may drive the internal circuit to rotate and affect the circuit layout. At the same time, the irregular shapes are in contact with the aluminum radiator 4, improving the sealing performance at the connection parts on both sides of the lamp cover 1 and preventing the entry of external liquids. On the left end cap 5 and the right end cap 6, there are circuit connection ports, and lamp holder copper pins 9 are arranged in the circuit connection ports, facilitating the connection with external circuits.

[0024] On the outer sides of the irregular shapes on the left end cap 5 and the right end cap 6, there are also threaded posts 602. The threaded posts 602 are square cylinders with threaded holes inside. At both ends of the ceramic heat dissipation plate 8, there are threaded holes located in a square groove. During installation, the square threaded posts 602 are inserted into the square groove, the two threaded holes are aligned, and they are fixed by radiator screws 11, thus realizing the fixation between the ceramic heat dissipation plate 8, the left end cap 5, and the right end cap 6.

[0025] At both ends of the inner side of the opening of the lamp cover 1, there is a groove, which is a mortise. On both sides of the ceramic heat dissipation plate 8, there are raised parts with a certain angle upwards to form tenons. During installation, the tenons on the ceramic heat dissipation plate 8 are inserted into the mortises on the lamp cover 1, thus improving the sealing performance at the connection part between the lamp cover 1 and the ceramic heat dissipation plate 8.

[0026] During product installation, first insert the circuit component fixing plate from the opening of the clamping groove 403 at both ends of the aluminum radiator 4 until the circuit component fixing plate is completely inserted. Then insert the light-emitting lamp strip 3 into the positioning groove 402 at both ends of the aluminum radiator 4, and complete the connection of the circuits of the inserted light-emitting lamp strip 3 and the control circuit 7 on the circuit component fixing plate. Then fix the aluminum radiator 4 on the ceramic heat dissipation plate 8 through the fitting groove 404 and the limiting strip 801. Next, connect the lamp cover 1 and the ceramic heat dissipation plate 8 in a snap-fit manner, and place the left end cap 5 and the right end cap 6 in their corresponding positions. When placing the left end cap 5 and the right end cap 6, pull out the internal circuit connection wires from the circuit connection ports. Finally, fix with screws to achieve overall fixation. When replacing components, disassemble the landscape lamp by reverse operation to replace the damaged components.

[0027] In this embodiment, by separating the outer shell from the internal components, the separate replacement of internal components can be realized without replacing the entire landscape lamp, reducing the usage cost. In this embodiment, by setting mortise and tenon structures at the connection parts of each component of the outer shell, without affecting the connection strength, the sealing performance at the connection parts is improved, avoiding the entry of external water vapor into the interior of the landscape lamp. In this embodiment, the driver and the light source are integrated, achieving no stroboscopic effect. On the light-emitting lamp strip 3 in this embodiment, there is a special LED protection shell, which can prevent fog from forming on the surface of the LED and can also extend the service life.

[0028] Embodiment Two:

[0029] In this embodiment, it mainly includes a housing and internal components, and the overall shape of the lamp body is cylindrical. The housing mainly includes a lamp cover 1, a left end cover 5, a right end cover 6, a ceramic heat dissipation plate 88, etc. The lamp cover 1 is cylindrical with openings at both ends and is sealed by the left end cover 5 and the right end cover 6. Approximately one-fourth of the side of the lamp cover 1 is also an opening, and this opening is sealed by the ceramic heat dissipation plate 88. The ceramic heat dissipation plate 88 is generally flat as a whole, and its size matches the opening on the side of the lamp cover 1, and it can just completely seal the opening. The lamp cover 1 is transparent as a whole, while the left end cover 5, the right end cover 6, and the ceramic heat dissipation plate 88 are all opaque, and the light inside the lamp body diverges from the lamp cover 1.

[0030] An aluminum heat sink 4 is provided inside the lamp body. The overall shape of the aluminum heat sink 4 is similar to that of the lamp cover 1, and there are some grooves on its surface. The connection line of its outermost border just coincides with the inner connection line of the lamp cover 1. Some of the grooves on the surface of the aluminum heat sink 4 are positioning grooves 402 for fixing the light-emitting lamp strips 3. The number of the positioning grooves 402 coincides with the number of the light-emitting lamp strips 3. In this embodiment, there are four light-emitting lamp strips 3, and the number of the positioning grooves 402 is also set to four and is evenly distributed. All the light-emitting lamp strips 3 are connected by lamp strip connectors to form a whole. The size of the positioning grooves 402 matches the shape and size of the light-emitting lamp strips 3. When the light-emitting lamp strips 3 are fixed in the positioning grooves 402, the blocking blocks that slightly extend from the top of the positioning grooves 402 to the inside of the groove body of the positioning grooves 402 can prevent the light-emitting lamp strips 3 from running out of the positioning grooves 402 and thus being misaligned. An aluminum heat sink 4 clamping groove 403 is provided inside the aluminum heat sink 4. The width of the clamping groove 403 matches the width of the circuit element fixing plate. The circuit element fixing plate is fixed in the clamping groove 403, thus presenting a relatively suspended state. On the side of the circuit element fixing plate facing the inner cavity of the aluminum heat sink 4, there are various components of the control circuit 7. Therefore, the control circuit 7 is located between the aluminum heat sink 4 and the ceramic heat dissipation plate 8, and can dissipate heat from the control circuit 7 to the greatest extent to protect the operation of the circuit.

[0031] On the upper positions of the openings on both sides of the outside of the aluminum heat sink 4, there are distributed and provided with a fitting groove 404 to form a right L-shaped barb. On the inner side of the ceramic heat dissipation plate 8, there are provided two parallel limiting strips 801. The limiting strips 801 can match the groove body shape of the fitting groove 404. During installation, the limiting strips 801 are fitted in the fitting groove 404 to prevent the position of the aluminum heat sink 4 from shifting.

[0032] On the inner sides of the left end cover 5 and the right end cover 6, there are irregular shapes protruding inwards. These irregular shapes match the shapes at both ends of the aluminum radiator 4, allowing the aluminum radiator 4 to be just fitted into these irregular shapes, preventing the aluminum radiator 4 from rotating, which could otherwise drive the internal wires to rotate and affect the wire routing. At the same time, these irregular shapes are in contact with the aluminum radiator 4, improving the sealing performance at the two connection points on both sides of the lamp cover 1 and preventing the entry of external liquids. On both the left end cover 5 and the right end cover 6, there are wire connection ports, and lamp holder copper pins 9 are provided in the wire connection ports, facilitating the connection with external wires.

[0033] On the outer sides of the irregular shapes on the left end cover 5 and the right end cover 6, there are also threaded posts 602. The threaded posts 602 are in the shape of square columns with threaded holes inside. At both ends of the ceramic heat dissipation plate 8, there are threaded holes located within a square threaded groove 802. During installation, the square threaded posts 602 are inserted into the square threaded groove 802, and the two threaded holes are aligned and fixed with radiator screws 11, thus achieving the fixation between the ceramic heat dissipation plate 8, the left end cover 5, and the right end cover 6.

[0034] On the outer sides of the irregular shapes of the left end cover 5 and the right end cover 6, there are installation grooves 601. On the aluminum radiator 4, there is a fixing groove 401. The width of the installation groove 601 is greater than the width of the fixing groove 401. During installation, the plastic strip 2 is inserted into the installation groove 601 and the fixing groove 401. The two ends of the plastic strip 2 are wider than the middle position, and the overall shape matches the shapes of the installation groove 601 and the fixing groove 401. At the positions corresponding to the installation grooves 601 on the left end cover 5 and the right end cover 6, there are holes. After the plastic strip 2 is inserted into the installation groove 601 and the fixing groove 401, it is fixed to the plastic strip 2 by passing the end cover screws 10 through these holes. The plastic strip 2 can form a whole with the left end cover 5, the right end cover 6, and the aluminum radiator 4, improving the overall strength and the sealing performance at the connection points.

[0035] At both ends of the inner side of the opening of the lamp cover 1, there is a groove, which is a mortise. On both sides of the ceramic heat dissipation plate 8, there are raised parts with a certain angle upwards, forming tenons. During installation, the tenons on the ceramic heat dissipation plate 8 are inserted into the mortises on the lamp cover 1, thus improving the sealing performance at the connection between the lamp cover 1 and the ceramic heat dissipation plate 8.

[0036] When installing the product, first insert the circuit element fixing plate from the opening of the clamping grooves 403 at both ends of the aluminum radiator 4 until the circuit element fixing plate is completely inserted. Then insert the light-emitting strip 3 from both ends of the aluminum radiator 4 into the positioning grooves 402, and complete the connection of the inserted light-emitting strip 3 and the circuit of the control circuit 7 on the circuit element fixing plate. Then fix the aluminum radiator 4 on the ceramic heat sink 8 through the fitting groove 404 and the limiting strip 801. Next, place the left end cover 5 and the right end cover 6 in their corresponding positions. When placing the left end cover 5 and the right end cover 6, pull out the internal circuit connection wire from the circuit connection port and install the plastic strip 2, and then snap the lamp cover 1 onto the ceramic heat sink 8. Finally, fix the end cover screws 10 and the radiator screws 11 to achieve overall fixation. When replacing components, disassemble the landscape lamp by reverse operation to replace the damaged components.

[0037] In this embodiment, by separating the housing from the internal components, the separate replacement of the internal components can be realized without replacing the whole landscape lamp, thus reducing the use cost. In this embodiment, mortise and tenon structures are arranged at the joints of the various parts of the housing, which can improve the sealing performance of the joints without affecting the connection strength and prevent external water vapor from entering the interior of the landscape lamp. The drive and the light source in this embodiment are integrated, and can achieve no stroboscopic effect. A special LED protection shell is arranged on the light-emitting strip 3 in this embodiment, which can prevent fog from forming on the surface of the LED and can also extend the service life.

[0038] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
